Changing Perceptions Of Science In Undergraduate Students: A Mixed Methods Case Study, Cindy S. Larson-Miller Aug 2011

Changing Perceptions Of Science In Undergraduate Students: A Mixed Methods Case Study, Cindy S. Larson-Miller

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

The purpose of this bounded single-case study was to explore the understanding of the nature and process of science for undergraduate students at the University of Nebraska-Lincoln (UNL). The study investigated one professor’s methodology to explicitly teach undergraduate students about the nature and process of science, and documented their understanding and perception of science, both pre- and post-course.

Using a mixed method approach, data were collected to provide a better understanding of teaching the nature and process of science. Three main types of data were analyzed: the process of science (TPOS) assessment; survey questions, and the module curriculum.

Extensiveness And Perceptions Of Lecture Demonstrations In The High School Chemistry Classroom, Daniel S. Price Jun 2011

Extensiveness And Perceptions Of Lecture Demonstrations In The High School Chemistry Classroom, Daniel S. Price

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

While lecture demonstrations have been conducted in chemistry classrooms for hundreds of years, little research exists to document the frequency with which such demonstrations are employed or their effect on learners’ motivation and performance. A mixed-methods research study was performed, using quantitative and qualitative survey data, along with qualitative data from follow-up interviews and structured correspondence, to determine the extent to which lecture demonstrations are used in high school chemistry instruction, and the perceived effects of viewing such demonstrations on students’ performance on course assignments and on motivation to excel in current and future chemistry courses. Fifty-two randomly selected chemistry ...
